Something on Toadstool Leather

[Tocspaw]

Tonight after lights out I noticed this tube like creature on the face of my toadstool leather. It is soft and has a mucus web coming from it that it can retract. Should I remove this, and if so, how?

Scrape it off. Tweezers...
Looks like a vermatid snail but that would have a calcified tube.
